CHARLES E. POPE, OF THC LYOKE, MASSACHUSETTS;

AU'TCSHATIC PAPEB-MACHDJE.

Application filer April 1915. Bcrial 210. 39,038.

To all whom it may concern t 1 r Be 1!; Known that L Qimnmcs b. l urn,a.

I citizen of the United States of America, re-

siding in the city of i'iolyoke, county of Hampden, and State ofMassachusetts; have invented certain new and useful Improvements inAutomatic.Paper-Machines, "of which the following is a specification. i

' This invention relates to a fast running paper machine andparticularly to improved 3 means and arrangements of parts whereby theweb is transferred automatically from the squeeze or ress .rolls to thedriers.

The object 0 the invention is to provide an improved arrangement ofparts by which the paper making machine may automatically transfertheforward endof a fast running web from the last squeeze rolls to thefirst drier characterized in the provision of positively acting means toforce the web '-'to follow the bottom felt from the last squeeze r llsto a point adjacent the first drier, a guiding means between the firstdrier and the point where the forward travel of the bottom felt ends towhich the running web may jump from tlie feltand mean'sto automaticallyforce the forward end of the. web fromthe guiding means'to and. be

tween the first drier audits felt.

Other objects will appear in the detailed description and annexe-dclaims.

. A preferred embodiment of my invention is shown in theaccompanyingdrawings for illustrative purposes and will now be described In thedrawings: Figure l is a diagram matic view of the arrangementof theparts of my invention; Fig. 2 is a side elevation of a paper makingmachine, showing only the arts thereof pertinent to an underfian of theinvention by those skilled Y in the art; Fig. 3 is a diagrammatic detail"view of a modification of one feature of the invention; Fig. l is adetail plan View of one feature of the invention associated with thelast squeeze rolls; Fig. 5 is a detail sectional view taken on ..theline 55 of F 4. V ghe features of the invention bywhicli on the start ofthe machine the web is automatically transferred from the lowerfelt tothe driers will first be described. As well known by those skilled inthe art the web, at the start or after any break in the process ofmaking the paper,'must be car- 'ried through the machine and fed to theSpecification of Letters Patent.

driers either by hand or automatically.

Rather than handle the entire .width of the web it is customary to formon the wire a ribbon which is carried through the machine and afterwardleads the web of full width for the normal operation.

Referring to F igsl 1 2, 4, and 5, the last 7 squeeze rolls 1 and-2receive therebetween zthe lower felts; with theweb Y (at. first-a-ribbon) thereon. -The' top roll 2' is bare so that there is a tendencyfor the web to stick I:

to this roll. Howevenbefore the ribbon has followed the roll 2 anysubstantialdistance it meets arevolving brush13iarran'ged' to, rotateoppositely 'to roll 2 at one side "(the side along which the ribbon: iscustomarily j; i fed); This brush 3 preferably of wire bris ties stripsthe .ribbon from" the roll and thro vs it down on thefelt .fl. Thelatter is guided horizontally beyond the squeezerolls to guide roll 5adjacent the periphery Qftlle first drier l1 where it returns overotherrolls 5. In line with the upper roll5 and Y between'it and thefirst drier ll-is a guide '80 roll 30 supplied with a'doctor 31; Aboveand a little beyond the ro lll30 is a horizontally arranged pipe 32connected to a source of air under pressure. downwardly directed outletas indicated in Flg.'1. v V

' Now if it is assumed that the machine is a fast running one the ribbon6 is loosened from the roll 2 by brush '3 and the loosened vend iscarried by the felt 4 horizontally so that it jumps the distance betweenadjacent This. pipe has arolls 5 and 30 and into line with "thedownwardlydirected blast from pipe 32. The

latter forces or blows it downwardly be tween the bight of driercylinder 11 and its' felt 9 whereupon the ribbon is pulled down andaround roll 30. 'If for any reason it should start to 'wind on roll 30the doctor 31 will strip it other. a' point above its proper entrance ondrier 11. .Thus the paper is automatically and efiicientlytransferredfrom the squeeze rolls to the first drier by improved means.-

The manner-of mounting and rotating the brush 3 is shown in Figs. fl:and 5. An

arm 15 pivoted to the side frame Am 17 has i a horizontal bearing inwhich is mounted the shaft of brush 3. On the outer end of the brush isa pulley driven by any suitable driving means as 18 and 22. The brushmay be positioned by swinging arm 15 and clamping it as desired to frameA.

' A modification isshown'in Fig.- 3 in which the web 6 jumps from felt 4to the bight of suitably driven pressure rolls 19 and 21.

The latter is made of rubber or an equi\'a-- have an improved appearanceor finish.

A brush 8 bears against roll QO and oper ates in conjunctionwith thisroll in all respects like the brush'3 already described and of which itmay be a counterpart. If the web starts to wind on roll brush 8 willthrow it down to enter'the bight of drier 11 and its felt 9. Adoctor'onroll 19 is positioned to prevent the web from winding on this roll. Inany case the web is directed downwardly for proper application to thefirst drier.

The improved arrangement of the drying cylinders will now be described.As indicated in Figs. 1 and 2 each lower cylinder 11 of a series islocated with its a.\'is vertically below its companion cylinder of theupper series. The upper and lower cylinders are arranged only a smalldistance apart or in such a way that the forward end of the web orribbon as it runs rapidly through the machine may jump from the lowercylinder to the bight of the upper one and its felt without climbing anappreciable distance and thus be transferred by its momentum. To thisend a doctor 40, Fig. 1, is arranged to strip the ribbon from cylinder11 as it reaches its upper horizontal'travel. The lower guide roll 41f0" felt 14 directs the latter to cylinder 12 from a point just back oftliedoctor 40 so that as the ribbon 6 leaves drier 11 it will jump tothe felt 14 traveling rapidly to drier,12 and be directed' and carriedto the latter dricr, and

this result is automatically obtained without the interposition of anystructure not herc tofore found in driers, but by an improvedarrangement of the old structure. or ribbon G is stripped from drier 12by a doctor as it is traveling thereon vertically and downwardly. Theupper left hand guide rollers and lower right hand guide rolls 41 forthe lower and upper felts 9 and 14, respectively, are mounted close totheir respective dryin cylinders 11 and 12 as shown. The we 6,therefore, in passing from the upper driers to the lower driers travelsautomatically and freely exposed on both sides a vertical distance fromone drier to another about equal to that between the axes of the upperand lower driers. The free space on both sides of the exposed web rmitsthe vapor, which would otherwise b: imprisoned to a large drgrce withthe The web.

-table brush mounted to bear web, to escape and thus advance the dryingoperation.

In addition to the automatic transferring feature of the invention fromone drier to the succeeding one and the other advantages 1 of thearrangement described it is clear that a considerable amount of floorspace is saved by mounting each pair of driers substantially one abovethe other as described,

\Vhere the driersare arranged as hereto- 7'5 fore in staggered or zigzag relation the dis tanee of at least the diameter of one cylinder 15necessary for a given number of driers,

in excess of the space required for the improved arrangement described.This improved arrangement of drying cylinders is not claimed as a partof this invention but forms the subject-matter of my copendingapplication, Serial No. 82,409, filed Mar. 6 1916. i i

It is not thought necessary to use any space indescribing the drivingconnections for the several parts or specific manner of mounting them inthe machine. From the drawings. and description disclosed one skilled inthe art can readily put the inven-' tion into use. The invention isdefined in its proper scope by the appended claims rather than by theforegoing specific description; '95 I What I claim is v V 1.
